Somehow the speakers stopped working, and the headphone output added a loud hiss. Unfortunately, I was unable to fix it. + +My first thought was to reinstall the system, but then I remembered that I've read about [ZFS Snapshots](https://docs.oracle.com/cd/E19253-01/819-5461/gbcya/index.html). + +``` +zfs list -t snapshot +``` + +revealed that FreeBSD has already created a few of those recently. I knew this OS and ZFS go hand in hand, but I was still pleasantly surprised. + +To return the system to a previous version, all I had to do was + +``` +zfs snapshot <name> +``` + +and my system stopped responding. I was in X, so that's entirely on one. But the rollback was so instantaneous that my first thought was that something fried. + +After a good, old hard reset, everything worked as it was a few days ago. ZFS very well may be my new best friend. diff --git a/resources/_gen/images/zfs-logo_hu73e89407e3aa5dae3d1372791b2ee1d9_66759_150x0_resize_q75_h2_box_3.webp b/resources/_gen/images/zfs-logo_hu73e89407e3aa5dae3d1372791b2ee1d9_66759_150x0_resize_q75_h2_box_3.webp Binary files differ. diff --git a/resources/_gen/images/zfs-logo_hu73e89407e3aa5dae3d1372791b2ee1d9_66759_300x0_resize_q75_h2_box_3.webp b/resources/_gen/images/zfs-logo_hu73e89407e3aa5dae3d1372791b2ee1d9_66759_300x0_resize_q75_h2_box_3.webp Binary files differ.
